TECHNICAL FIELD

The present invention relates to an apparatus for recording informationconcerning the use of an injection device and relates particularly, butnot exclusively, to an apparatus for recording information concerningthe use of an injection device which is used to inject medicament suchas insulin.

BACKGROUND

A variety of diseases exist which require regular treatment by injectionof a medicament. Such injection can be performed by either medicalpersonnel or by patients themselves. As an example, type-1 and type-2diabetes can be treated by patients themselves by injection of insulindoses once or several times per day. It is known to couple asupplemental device to an insulin injection device for recordinginformation about the doses which are administered. Supplemental devicesmay be used to record information about the various times at whichinsulin is administered and the quantity of insulin which isadministered at each such time.

Some supplemental devices are not capable of displaying informationabout previously administered doses (or at least do not display all ofthe information they record). Dose history information may instead onlybe accessed using proprietary software on a computer which a person maynot have access to at all times. The situation could therefore arisethat a person cannot administer future doses on the basis of informationconcerning previously administered doses. In particular if a user wereto forget how much insulin has been previously administered, and whenthe last injection took place, they will be required to guess theappropriate time of their next insulin dose and the quantity of insulinto be injected which is highly undesirable.

Aspects of the present invention have been conceived with the forgoingin mind.

SUMMARY

According to an aspect of the present invention there is providedapparatus for recording information concerning the use of an injectiondevice, the apparatus comprising: one or more sensors for providinginformation indicative of how the injection device is used; a processorconfigured to analyse said information detected by the one or moresensors to determine use information, said use information correspondingto how the injection device is used; and a memory for storing said useinformation in an image format such that said use information can beretrieved from the memory and displayed in an image.

Advantageously, this improves the ease with which use information can beaccessed since it is more likely that a device capable of displayingimages will be accessible at a given time than a computer which hasstored thereon proprietary software for both analysing and displayingdata which concerns the use of an injection device.

The apparatus may be a supplemental device provided with a part forcoupling the supplemental device to said injection device and the one ormore sensors may be for detecting information displayed or generated bythe injection device.

Advantageously, this enables the apparatus to be used in conjunctionwith an existing injection device.

The apparatus may be an integral part of said injection device.

Advantageously, this provides an injection device with enhancedfunctionality.

The memory may be configured to store said use information in a lossyimage format. The memory may be configured to store said use informationin raster format, vector format, compound format or stereo format. Thememory may be configured to store said use information in .JPEG format.

The apparatus may further comprise a transmitter for wirelesslytransmitting said use information to a remote device.

The memory may comprise a storage device that is removable from saidapparatus.

The apparatus may further comprise an interface for receiving thestorage device.

The memory may comprise another storage device that is not removablefrom said apparatus.

The processor may be configured to copy information from one storagedevice to another of said storage devices.

The apparatus may further comprise one or more user interface featuresthat may be manipulated to cause the processor to copy information fromone said storage device to another of said storage devices.

DETAILED DESCRIPTION

In the following, embodiments of the present invention will be describedwith reference to an insulin injection device. The present invention ishowever not limited to such application and may equally well be deployedwith injection devices that eject other medicaments, or with other typesof medical devices.

FIG. 1 is an exploded view of an injection device 1, which may forinstance represent Sanofi's Solostar® insulin injection pen.

The injection device 1 of FIG. 1 is a pre-filled, disposable injectionpen that comprises a housing 10 and contains an insulin container 14, towhich a needle 15 can be affixed. The needle is protected by an innerneedle cap 16 and an outer needle cap 17, which in turn can be coveredby a cap 18. An insulin dose to be ejected from injection device 1 canbe selected by turning the dosage knob 12, and the selected dose is thendisplayed via dosage window 13, for instance in multiples of so-calledInternational Units (IU), wherein one IU is the biological equivalent ofabout 45.5 micrograms of pure crystalline insulin ( 1/22 mg). An exampleof a selected dose displayed in dosage window 13 may be 30 IUs, as shownin FIG. 1 . It should be noted that the selected dose may equally wellbe displayed differently, for instance by means of an electronicdisplay.

Turning the dosage knob 12 causes a mechanical click sound to provideacoustical feedback to a user. The numbers displayed in dosage window 13are printed on a sleeve that is contained in housing 10 and mechanicallyinteracts with a piston within the insulin container 14. When needle 15is stuck into a skin portion of a patient, and then injection button 11is pushed, the insulin dose displayed in display window 13 is ejectedfrom injection device 1. When the needle 15 of injection device 1remains for a certain time in the skin portion after the injectionbutton 11 is pushed, a high percentage of the dose is actually injectedinto the patient's body. Ejection of the insulin dose also causes amechanical click sound, which is however different from the soundsproduced when using dosage knob 12.

Injection device 1 may be used for several injection processes untileither insulin container 14 is empty or the expiration date of injectiondevice 1 (e.g. 28 days after the first use) is reached.

Furthermore, before using injection device 1 for the first time, it maybe necessary to perform a so-called prime shot to remove air frominsulin container 14 and needle 15. This may be achieved by selectingtwo units of insulin and pressing injection button 11 while holdinginjection device 1 with the needle 15 pointing upwards.

For simplicity of presentation, in the following, it will be exemplarilyassumed that the ejected doses substantially correspond to the injecteddoses, so that, for instance when making a proposal for a dose to beinjected next, this dose equals the dose that has to be ejected by theinjection device. Nevertheless, differences (e.g. losses) between theejected doses and the injected doses may of course be taken intoaccount.

FIG. 3 is a schematic illustration of a supplemental device 2 which maybe releasably attached to an injection device such as the one depictedin FIG. 1 for instance. It is envisaged however that the supplementaldevice 2 may be coupled to and used in conjunction with other types ofinjection devices of other types, and for administering differentmedicaments.

The supplemental device 2 comprises a housing 20 which is provided witha mating unit 20-1, 20-2 for embracing the housing 10 of an injectiondevice. In particular the mating unit 20-1, 20-2 may be configured tosnap-fit onto the housing 10 of an injection device 1 in such a way thatthe device 2 can be subsequently removed therefrom. The mating unit neednot however be of the snap-fit variety and other arrangements mayalternatively be suitable for coupling the supplemental device 2 to aninjection device 1 such as a strap.

When coupled to an injection device 1, the supplemental device 2 may becaused to obstruct the dosage window 13 (as in FIG. 6 ). A supplementaldevice 2 configured to be used in this way contains one or more sensors,for example optical and/or acoustical sensors 25, 27 which gatherinformation from the injection device 1. In particular the opticalsensor(s) 25 gather information which is displayed in the dosage window13. Such gathered information may then subsequently be displayed bydisplay unit 21 provided on the supplemental device 2.

The supplemental device 2 further comprises one or more transducers forreceiving user input, illustrated schematically as a single button 22 inFIG. 3 although a plurality of buttons may be provided instead as shownin FIGS. 4 and 6 . Such input transducers may by used, inter alia, toturn on/off the supplemental device 2, trigger actions (which mayinvolve causing the supplemental device 2 to pair or establish aconnection with another device, and/or causing the device 2 to transmitinformation to another device), or to confirm something.

FIG. 4 depicts a perspective view of a supplemental device 2 accordingto one envisaged embodiment. The device 2 is coupled to an injectiondevice 1 via a mating unit (not shown). As illustrated, informationdetermined by the device 2 may be displayed using display unit 21. Itwill be appreciated that the dosage window 13 of the illustratedinjection device 1 is obstructed by the supplemental device 2.

The embodiment depicted in FIG. 4 has three user input buttons (orswitches). A first such button 22 a is a power on/off button, actuationof which may cause the supplemental device 2 to be turned on and/or off.A second button 22 b is a communications button actuation of which maycause the supplemental device 2 to pair or establish a connection withanother device such as a computer (using Bluetooth for example). A thirdbutton 22 c is a confirm or OK button actuation of which may be used toindicate a user's desired selection. The buttons 22 a, 22 b, 22 c may beany suitable form of mechanical switch, electrical transducer switch, orelectromechanical switch.

FIG. 5 depicts a perspective view of a supplemental device 2 accordingto another embodiment. The device is coupled to an injection device 1via a mating unit (not shown). Information determined by the device 2may be displayed using display unit 21. It will be appreciated that thedosage window 13 of the illustrated injection device 1 is obstructed bythe supplemental device 2.

The embodiment depicted in FIG. 5 has a touch-sensitive transducer 35for receiving user input. The device 2 is also provided with a singleuser input button (or switch 22). Actuation of the button 22 may causethe supplemental device 2 to be turned on and/or off. Manipulation ofthe touch sensitive input transducer 35 may trigger other actionsinvolving, inter alia, causing the device 2 to pair or establish aconnection with another device, triggering transmission of informationfrom the supplemental device 2 to another device, and/or confirmingsomething such as a user's desired selection.

FIG. 6 illustrates an internal schematic view of a supplemental device 2of the kind depicted in FIG. 4 in a state where it is coupled to aninjection device 1.

Within the housing 20 of the supplemental device 2, a variety ofcomponents are located. These are controlled by a processor 24 which mayfor instance be a microprocessor, a Digital Signal Processor (DSP),Application Specific Integrated Circuit (ASIC), Field Programmable GateArray (FPGA) or the like. Processor 24 executes program code (e.g.software or firmware) stored in a program memory 240, and uses a mainmemory 241, for instance to store intermediate results. Main memory 241may also be used to store a logbook on performed ejections/injections.Program memory 240 may for instance be non-volatile memory, such asRead-Only Memory (ROM), and main memory may for instance be a volatilememory, such as Random Access Memory (RAM). A logbook on performedejections/injections may alternatively be stored in a flash memorycoupled to the processor 24.

Upon actuation of the aforementioned first button 22 a the processor maybe sent a signal indicting that the supplemental device 2 is to beturned on and/or off. Actuation of the second button 22 b (thecommunications button) may cause a signal to be sent to the processor,initiating the processor 24 to establish a connection between thesupplemental device 2 and another device, or to trigger transmission ofinformation from the supplemental device 2 to another device. A thirdbutton 22 c is a confirm or OK button upon actuation of which theprocessor 24 may be sent a signal indicting a user's desired selectionor confirmation. The third button 22 c may be used to acknowledgeinformation presented to a user of supplemental device 2, for example onthe display unit 21.

In other embodiments such as the one depicted in FIG. 5 , two of thebuttons 22 b, 22 c may be omitted. Instead one or more capacitivesensors or other touch sensors may be provided.

Processor 24 is configured to control a display unit 21, which may be aLiquid Crystal Display (LCD) for example. The display unit 21 may beused to display information to a user of supplemental device 2. Examplesof such information may include the present settings of the injectiondevice 1, or information concerning a next injection to be given forinstance the time remaining until when a next injection should beadministered. The display unit 21 may be a touch-screen display forreceiving user input and transferring it to the processor 24. Thetouch-sensitive transducer 35 in FIG. 5 may be part of such atouch-screen display.

The supplemental device 2 may be provided with an optical sensor 25 forreading information provided on the sleeve 19 through the dosage window13. Such information may comprise numbers or other markings located onthe sleeve 19 which indicate an amount of dose which has been dialled oris yet to be dispensed. The optical sensor 25 may be an OpticalCharacter Recognition (OCR) reader that is capable of capturing imagesof the dosage window 13 in which a currently selected dose is displayed.The OCR reader 25 is further capable of recognizing characters (e.g.numbers) from the captured image and providing this information toprocessor 24.

Alternatively, the optical sensor 25 may be configured to merely captureimages and provide information corresponding to such images to theprocessor 24. In such an arrangement the optical sensor 25 may be acamera and the processor 24 may be configured to perform theaforementioned OCR on the captured images.

The processor 24 constitutes a processor arrangement. The abovementioned OCR reader 25 may constitute a dose dialled detector operableto detect a dose of medicament dialled. The OCR reader 25 may alsoconstitute a dose delivery determiner for determining that a dose ofmedicament has been delivered. The OCR reader 25 and the processor 24may together constitute a quantity determiner for determining a quantityof medicament that has been delivered (and/or is yet to be dispensed, ifany). The processor 24 provides a function of a clock configured todetermine a current time.

A battery 32 powers the processor 24 and any other components comprisingpart of the supplemental device 2 by way of a power supply 31. Suchother components will now be described. It will be appreciated that notall such other components are essential and a person skilled in the artmay choose to omit one or more such components from a supplementaldevice. For example a supplemental device 2 may be made without thephotometer 26 and/or pen detection switch 30 (both of which aredescribed below).

The supplemental device 2 may be provided with a light-source, forexample one or more light emitting diodes (LEDs) 29, to illuminate thedosage window 13 in which a currently selected dose is displayed. Theprocessor 24 may be configured to control operation of such a lightsource. Furthermore, a diffuser may be provided in front of thelight-source(s), for instance a diffuser made from a piece of acrylicglass. Additionally, the optical sensor 25 may comprise a lens (e.g. anaspheric lens) leading to a magnification (e.g. a magnification of morethan 3:1).

The supplemental device 2 may be provided with a photometer 26 fordetermining an optical property of the housing 10 of injection device 1,for example a colour or a shading. The processor 24 may be configured toreceive a signal from the photometer 26, thereby enabling the processor24 to determine the particulars of said optical property. The opticalproperty may be present in a specific portion of the housing 10. Forexample a colour or colour coding may be provided on the sleeve 19 or aninsulin container comprised within the injection device 1. Also, thecolour or colour coding may be visible through a further window in thehousing 10 (and/or in the sleeve 19). Information relating to thiscolour may be provided to the processor 24 for determining the type ofinjection device 1 or the type of insulin contained within the injectiondevice (e.g. SoloStar® Lantus® with purple colour and SoloStar® Apidra®with blue colour).

The supplemental device 2 may be provided with an acoustical sensor 27for detecting sounds produced by an injection device 1. Such anacoustical sensor 27 may be used instead of or in conjunction with theoptical sensor 25 heretofore described. The processor 24 may beconfigured to control and/or receive signals from such an acousticalsensor 27. Sounds may for instance occur when a dose is dialled byturning the dosage knob 12 and/or when a dose is ejected/injected bypressing injection button 11, and/or when a prime shot is performed.These actions are mechanically similar but nevertheless sound differentwhen they are respectively performed (this may also be the case forelectronic sounds, produced by acoustical signal generator 23 forinstance, which indicate the occurrence of these actions). Theacoustical sensor 27 and/or the processor 24 may be configured todifferentiate between these different sounds in order to safelyrecognize that an injection has taken place (rather than merely a primeshot having been made).

The supplemental device 2 may be provided with a wireless unit 28 whichthe processor 24 may control in order to transmit information to, and/orreceive information from, another device in a wireless fashion. Suchtransmission/reception may be based on radio transmission or opticaltransmission for example. In particular the wireless unit 28 may be aBluetooth transceiver. Alternatively, the wireless unit 28 may besubstituted or complemented by a wired unit which is configured totransmit information to, and/or receive information from, another devicein a wire-bound fashion (such as via a cable or fibre connection). Whendata is transmitted, the units of the data (values) transferred may beexplicitly or implicitly defined. For instance, in case of an insulindose, always International Units (IU) may be used, or otherwise, theused unit may be transferred explicitly, for instance in coded form.

Lastly, the supplemental device 2 may be provided with a pen detectionswitch 30. Such a switch 30 may be operable to detect whether the pen 1is present (i.e. to detect whether the supplemental device 2 is coupledto an injection device 1). When a pen 1 is detected (i.e. thesupplemental device 2 is detected as being coupled to an injectiondevice 1), the pen detection switch 30 may output a signal to theprocessor 24.

The supplemental device 2 depicted in FIG. 4 is capable of determininginformation related to a condition and/or use of the injection device 1.Such information may comprise information that human operators (usersand/or medical practitioners) would be interested to be included in theaforementioned logbook on performed ejections/injections. Othersupplemental devices 2 however may not be provided with a display unit21 and may be configured to store information related to a conditionand/or use of the injection device 1 without causing it to be displayed.An example of one such supplemental device 2 is illustrated in FIG. 7 inthe form of an electronic module 33 that is capable of being fitted tothe rear of an injection device 1.

In view of the foregoing it will be appreciated that supplementaldevices 2 may be provided with one or different types of sensors fordetermining information relating to a condition and/or use of aninjection device 1. It will further be appreciated that the supplementaldevices 2 may be configured to cause such determined information to besaved in a storage space (for example main memory 241 or a removablememory card). In particular this information may comprise entries madein a logbook containing details of a dose history for a particular user.

Aspects of the invention described hereafter are not limited to thesupplemental devices 2 depicted in the drawings but apply equally tosupplemental devices for use with any kind of injection device, andsupplemental devices provided with any combination of sensors fordetecting information related to one or more conditions and/or use of aninjection device.

A supplemental device 2 may be provided with sensors which enable theprocessor 24 of such device to determine: i) the size of an insulin dosedelivered by an injection device; ii) the date and/or time when suchdose was delivered; and/or iii) the latest BGM (blood glucosemeasurement) reading of the user's blood. Information relating to theseparameters may be saved in a storage space located on the supplementaldevice (such as main memory 241 or a removable memory card) along withsimilar information determined at later or earlier times. Thisinformation collectively provides a dose history of the person using theinjection device to which the supplemental device is coupled.

Information concerning each separate dose may be saved in the abovementioned storage space in a format that is only readable by proprietysoftware. Such proprietary software may be utilised by the supplementaldevice, or a remotely located computer, to display and/or analyse dosehistory information. Additionally however (or instead) informationconcerning each separate dose may be saved in the storage space in animage format. Such an image format may be of either the lossy orlossless variety. Particular examples of image formats that may be usedinclude, inter alia, raster format, vector format, compound format andstereo format. The processor may achieve conversion into an image formatby taking the raw information relating to a dose, applying it to atemplate, and converting the completed template into an image file. Morespecifically information concerning each separate dose may be saved inthe storage space in .JPEG format or .BMP format.

Saving information concerning each separate dose in .JPEG format (JointPhotographic Experts Group format) is advantageous because the .JPEGformat is readable by a large array of commonly available electronicdevices. This is particularly useful if the supplemental device is notitself capable of displaying dose history information (or is onlycapable of displaying some but not all dose history information),thereby requiring this information to be displayed on an additionalelectronic device such as a computer. FIG. 8 illustrates an example of a.JPEG image depicting dose information.

A person skilled in the art will appreciate that there are many ways inwhich dose history information stored in an image format may betransferred to another electronic device that is capable of displayingimages. For example, the supplemental device may have a wireless unit 28of the kind described in connection with FIG. 6 . Such a wireless unit28 may be used to wirelessly transfer data relating to images, whichdepict dose information, to a remote device. Alternatively thesupplemental device may transfer data relating to images, which depictdose information, to a remote device via a cable or fibre connection.Such devices may be coupled via a USB interface for example.Furthermore, the storage space on which images that depict doseinformation are saved may be removable and connected to a remote devicewhich is capable of displaying images. Such a removable storage spacemay for example comprise an SD card, an XD card or a USB memory stick,and may co-operate with (or be received in) a complementary interfaceprovided on the supplemental device.

A removable storage space may serve as a secondary storage device inaddition to a primary (or main) storage device that cannot be removedfrom a supplemental device. Information may be copied between suchprimary and secondary storage devices. A supplemental device may haveone or more user interface features which upon manipulation cause aprocessor to copy information between the primary (non-removable) andsecondary (removable) storage devices. For example, if a supplementaldevice is provided with a display unit 21, a menu feature may bedisplayed asking the user to indicate whether or not they want to copyinformation from the primary storage device to the secondary storagedevice or vice versa. Such a menu feature may be caused to be displayedupon connection of a secondary storage device to the supplementaldevice. A user may indicate a positive or negative selection via a shortand/or long press of a particular combination of one or more transducersfor receiving user input such as a button 22 or a touch-sensitive pad ortransducer 35. In the case of supplemental devices that are not providedwith a display unit 21 (and even those which are) a user may indicatewhether or not they want to copy information between the primary andsecondary storage devices at any particular time via a short and/or longpress of a particular combination of one or more transducers forreceiving user input (as before such transducers may comprise a button22 or a touch-sensitive pad or transducer 35).

If images that depict dose information are stored on a memory card, suchimages may be displayed on any device that is capable of reading thatmemory card to view files stored thereon. Some particular examples ofdevices that are capable of reading memory cards include digitalcameras, computers, mobile phones, TVs and electronic photo frames.Advantageously, if a memory card is inserted into such an electronicdevice the files containing images, which depict dose information, willbe automatically displayed in date and time order. This enablesinformation concerning a particular dose to be quickly and easilylocated. FIG. 9 illustrates a plurality of such image files beingdisplayed in date and time order on a computer.

According to another aspect of the invention, the functionality of asupplemental device that is capable of storing dose information in imageformat may be implemented by an injection device. For instance, featureswhich correspond with those of a supplemental device heretoforedescribed may be integral parts of an injection device. In oneparticular example, features corresponding with those of a supplementaldevice which has an acoustical sensor 27 in place of an optical sensor25 may be integral parts of an injection device. Such injection devicesare capable of storing dose information in image format (for instanceJPEG format) in the manner previously described. It should be noted thatan injection device capable of storing dose information in image formatmay be provided with any combination of sensors for detectinginformation related to one or more conditions and/or use of theinjection device.

It will be appreciated that the above described embodiments are purelyillustrative and are not limiting on the scope of the invention. Othervariations and modifications will be apparent to persons skilled in theart upon reading the present application. For instance any kind ofinformation may be displayed in an image depicting information relevantto a particular dose. In particular, further to information picked upfrom the device sensor(s) other information which was relevant at thetime when a particular dose is administered may be included in theimage. Additional examples of information that may be included in animage depicting dose information (such as the one in FIG. 8 ) mayinclude a patient's name to whom a dose was administered and/or otherdetails of that patient, a medical practitioner's name responsible forthe patient using the injection device used, the type of insulin (orother medicament) delivered, the type of injection device used, arecommended amount of dose to be administered and an actual amount ofdose that was delivered.

Finally, it be appreciated that the functionality described herein whichrelates to the storage of information, detected by one or more sensors,in an image format applies to injection devices configured to inject anykind of medicament and not solely those used for injecting insulin.Moreover, the disclosure of the present application should be understoodto include any novel features or any novel combination of featureseither explicitly or implicitly disclosed herein or any generalizationthereof and during the prosecution of the present application or of anyapplication derived therefrom, new claims may be formulated to cover anysuch features and/or combination of such features.
